Lashing has been used as a means of installing since the process was developed by in the late 1940s. This process typically involves lashing one or more copper telephone cable, co-ax cable TV cable or fibre-optic cable to a pre-installed steel messenger wire using a steel lashing wire and a device called a 'spinner' or 'lasher'. OPAC cables can be installed on existing ground wires or phase conductors, even OPGW or OPCC to expand communications capacity. An optical fiber composite overhead ground wire (OPGW) is a new type of ground cable used in the high-voltage power transmission system that serves as both a conventional overhead ground cable and a communication optical cable. Because aerial cables are exposed to harsh outdoor environments and extreme weather conditions, their materials must be strong and durable.

Specifically designed to provide a rapid and secure fixing when erecting cable trays. The fixed washer to the flange nut prevents it from falling into the socket driver. The screw-on cable tray systems fulfil the requirements of "IEC 61537:2006 – Cable management – Cable tray systems and cable ladder systems" for the low-voltage area. This method primarily relies on two key accessories: hoisting frames and cross arms, each suited for different specifications of cable trays.
